Abstract (en)
[origin: WO2019243719A1] The invention relates to a method (10) for geolocating a terminal (70) of a wireless communication system (60). The terminal comprises a positioning device for obtaining a precise geographical position of the terminal. An access network (80) of the communication system is configured to estimate an approximate geographical position of the terminal. In order to limit the size of the messages exchanged between the terminal and the access network, only a truncated part of the information about the precise geographical position of the terminal is transmitted by the terminal to the access network. The access network is configured to determine the precise geographical position of the terminal by combining the truncated information received from the terminal with the approximate geographical position estimated by the access network.
